Nvidia chips become the first GPUs to fall to Rowhammer bit-flip attacks

Nvidia's RTX A6000 GPU is vulnerable to Rowhammer attacks, where hackers can manipulate data stored in memory by exploiting weaknesses in DRAM chip modules. Nvidia is recommending a mitigation that could reduce performance by up to 10% to protect users from potential exploits that could compromise work projects. This marks the first time GPUs have been targeted by Rowhammer attacks, which were previously demonstrated only against memory chips for CPUs. The vulnerability poses a risk to users of high-performance computing GPUs, prompting Nvidia to take action to safeguard against potential compromises.
